can't open workfile

[hhel1]

I use Eviews 7 and sometimes (not very often) I have problem to open workfiles. When I try to open the workfile I get the error message "File does not meet .WF1 workfile specification.". Before this happens I have opened the file successfully a lot of times. Why? Is it possible to rescue the file?
Thanks for a n useful forum.

This message indicates that the file has become corrupt somehow. This can often happen when saving large files across a network connection. In such cases it is often better to save it to your local drive first, and then copy it over to the network location.

When corruption does occur, you can always switch back to your backup copy of the file (the file with the same name and a ~f1 extension).

I tried to open the ~f1-file, but don't know what "Format string" to use in Binary read step 1 of 3.

Rename it to a .wf1 file first.

I made it! Thanks, it saved me a lot of work!
